| Abstract: | In order to discover new semidwarf genes which can be used in breeding program in indica rice, a dwarf variety Aitaiyin 2, was crossed with a tall native cultivar Naming 6. The segregation of the F1 generation appeared to be 9 tall:6 semidwarf:1 dwarf, which meant two semidwarf genes were involved. While Aitaiyin 2 was also crossed with two semidwarf varieties, Nanjing 11 with sd-1 and Xingui'ai with sd-g, the segregation of the F2 generation in the former cross was 3 semidwarf:1 dwarf and that in the latter cross was 27 tall:27 semidwarf:9 dwarf:1 extra dwarf. This indicated that there were two semidwarf genes in Aitaiyin 2, one of them was allelic to sd-1 and the other was a new semidwarf gene which was nonallelic to both sd-1 and sd-g. This new semidwarf gene was named sd-t(t). |
